Seismic Phase 4 of the Hammer Museum project will continue the seismic retrofit of the 16-story office tower on Wilshire Boulevard, which houses the museum on its lower five floors. The scope includes installing two steel and concrete moment frames at the building’s east and west ends, adding fiber reinforcement to concrete pilasters between the exterior windows and around the elevator shafts from the second floor to the lower basement, and integrating steel stiffening plates at existing perimeter structural steel column splices. Additionally, the seismic enhancements will extend down to the building’s below-grade foundations.
